Hats off to Tycho for blocking botnets automatically! Remember, it's causing a loss of 3% pool fees.
That's not how I read the screenshot. Look at the account's current hash rate, about 4 GH. So he's letting them get work and submit it, he's likely just made it so it isn't accumulating bitcoins for it - meaning instead of a 3% share of their work he's getting a 100% share of it.
No. In this "warning" state at the moment of taking this screenshot all account/workers configuration options are disabled, but mining still continues and he gets his reward.
Then if we don't receive any explanation from user, his workers are blocked and he won't get any work (his miners will stop).
Mining operations on this account were already blocked when I saw this topic.
This red message turned out to be a bit misleading, I'll correct it now.
